Method, device, and system of detecting a lie of a user who inputs data

1. A method comprising: monitoring input-unit gestures and interactions of a user that inputs data through an electronic device towards a computerized system; based on analysis of said input-unit gestures and interactions, determining that said user has inputted through said electronic device data that said user knows to be false in order to increase a benefit that said computerized system provides to said user; wherein said analysis comprises: (a1) presenting to said user a form having a plurality of multiple-choice questions, including therein a first multiple-choice question and a second multiple-choice question; (a2) defining, via at least one of: (A) a set of pre-defined rules, (B) a lookup table, that a particular type of choice change, that is performed in the first multiple-choice question in accordance with pre-defined timing rules and pre-defined context rules, is to be handled as a beautifying correction which increases the benefit that said computerized system provides to said user; (a3) defining, via at least one of: (A) said set of pre-defined rules, (B) said lookup table, that a particular type of choice change, that is performed in the second multiple-choice question in accordance with pre-defined timing rules and pre-defined context rules, is to be handled as a non-beautifying correction which does not increase the benefit that said computerized system provides to said user; (b1) detecting that said user selected a first choice in said first multiple-choice question, and then changed said first choice to a first replacement choice; (b2) based on definitions made in step (a2) with regard to said first multiple-choice question, and by taking into account at least a first context and a first timing in which step (b1) was performed, determining that changes that the user performed in step (b1) in the first multiple-choice question are a beautifying correction that was performed by said user via said electronic device in order to increase the benefit that said computerized system provides to said user, and triggering a determination that the first replacement choice is false; (c1) detecting that said user selected a second choice in said second multiple-choice question, and then changed said second choice to a second replacement choice; (c2) based on definitions made in step (a3) with regard to said second multiple-choice question, and by taking into account at least a second context and a second timing in which step (c1) was performed, determining that changes that the user performed in step (c1) in the second multiple-choice question are a non-beautifying correction which does not trigger a determination that the second replacement choice is false.

2. The method of claim 1 , wherein said method is implemented by a hardware processor which (I) does not have a-priori knowledge whether the first choice is true or false and (II) does not have a-priori knowledge whether the second choice is true or false.

3. A system comprising: one or more processors, operably associated with one or more memory units, wherein the one or more processors are configured to: monitor input-unit gestures and interactions of a user that inputs data through an electronic device towards a computerized system; based on analysis of said input-unit gestures and interactions, determine that said user has inputted through said electronic device data that said user knows to be false in order to increase a benefit that said computerized system provides to said user; wherein in analysis, said one or more processors are operable to: (a1) present to said user a form having a plurality of multiple-choice questions, including therein a first multiple-choice question and a second multiple-choice question; (a2) define, via at least one of: (A) a set of pre-defined rules, (B) a lookup table, that a particular type of choice change, that is performed in the first multiple-choice question in accordance with pre-defined timing rules and pre-defined context rules, is to be handled as a beautifying correction which increases the benefit that said computerized system provides to said user; (a3) define, via at least one of: (A) said set of pre-defined rules, (B) said lookup table, that a particular type of choice change, that is performed in the second multiple-choice question in accordance with pre-defined timing rules and pre-defined context rules, is to be handled as a non-beautifying correction which does not increase the benefit that said computerized system provides to said user; (b1) detect that said user selected a first choice in said first multiple-choice question, and then changed said first choice to a first replacement choice; (b2) based on definitions made in step (a2) with regard to said first multiple-choice question, and by taking into account at least a first context and a first timing in which step (b1) was performed, determine that changes that the user performed in step (b1) in the first multiple-choice question are a beautifying correction that was performed by said user via said electronic device in order to increase the benefit that said computerized system provides to said user, and triggering a determination that the first replacement choice is false; (c1) detect that said user selected a second choice in said second multiple-choice question, and then changed said second choice to a second replacement choice; (c2) based on definitions made in step (a3) with regard to said second multiple-choice question, and by taking into account at least a second context and a second timing in which step (c1) was performed, determine that changes that the user performed in step (c1) in the second multiple-choice question are a non-beautifying correction which does not trigger a determination that the second replacement choice is false.

4. The system of claim 3 , wherein said one or more processors (I) do not have a-priori knowledge whether the first choice is true or false and (II) do not have a-priori knowledge whether the second choice is true or false.

5. A system comprising: one or more processors, operably associated with one or more memory units, wherein the one or more processors are configured to: monitor input-unit gestures and interactions of a user that inputs data through an electronic device towards a computerized system; based on analysis of said input-unit gestures and interactions, determine that said user has inputted through said electronic device data that said user knows to be false in order to increase a benefit that said computerized system provides to said user; wherein in said analysis, the one or more processors are operable to: (a1) present to said user a form having a plurality of data-entry fields, including therein a first data-entry field and a second data-entry field; (a2) define, via at least one of: (A) a set of pre-defined rules, (B) a lookup table, that a particular type of changes to data, that is entered in said first data-entry field in accordance with pre-defined timing rules and pre-defined context rules, is to be handled as a beautifying correction which increases the benefit that said computerized system provides to said user; (a3) define, via at least one of: (A) said set of pre-defined rules, (B) said lookup table, that a particular type of changes to data, that is entered in said second data-entry field in accordance with pre-defined timing rules and pre-defined context rules, is to be handled as a non-beautifying correction which does not increase the benefit that said computerized system provides to said user; (b1) detect that said user typed via a keyboard a first value into said first data-entry field, and then changed said first value to a first replacement value; (b2) based on per-field definitions made in step (a2), and by taking into account at least a first context and a first timing in which step (b1) was performed, determine that changes that the user performed in step (b1) in the first data-entry field, are a beautifying correction that was performed by said user via said electronic device in order to increase the benefit that said computerized system provides to said user, and triggering a determination that the first replacement value is false; (c1) detect that said user typed via said keyboard a second value into said second data-entry field, and then changed said second value to a second replacement value; (c2) based on per-field definitions made in step (a3), and by taking into account at least a second context and a second timing in which step (c1) was performed, determine that changes that the user performed in step (c1) in the second data-entry field, are a non-beautifying correction which does not trigger a determination that the second replacement value is false.

6. The system of claim 5 , wherein said one or more processors (I) do not have a-priori knowledge whether the first choice is true or false and (II) do not have a-priori knowledge whether the second choice is true or false.
